The City's liquid waste ordinance was passed in 1986 and regulates the generation, transportation, and disposal of liquid waste, i.e. grease trap, sand/grit trap, chemical toilet, and septic system wastes.

Through the annual permitting process, the Environmental Services Department ensures all liquid waste disposal companies operating within Grand Prairie have current state and city permits, maintain accurate documentation of manifests required for generation, transportation and disposal of wastes, and maintain equipment.

Approximately 100 vehicles are permitted yearly. The cost is $200 for each truck.  In addition, transporters are required to purchase manifest books, unless they are only transporting waste from chemical toilets. In this case, they must submit quarterly reports documenting the date of transport, volume transported, and disposal sites.
